Blueberry Auto in Organic Soil w/ LED

Sept 13 (Day 8): Watered for the first time. Tap water left on the counter for 18 hours to dechlorinate and then PHed down with white vinegar to 6.3 Days 9-13: Slowly increased PAR levels from ~370 up to ~430. The presoaked soil was still damp all week, and the weather was quite humid, so I only watered once this week -- 0.5L each plant on day 13. Tap water was kept overnight on the counter to dechlorinate and then PH down with half a teaspoon of white vinegar to about 6.2. This grow is already doing so much better than my first one and the only real difference is I'm not overwatering them. I'm holding back and letting the roots search for moisture and grow and I can see the difference already. In the coming weeks, I'll need to increase my watering amounts and frequency, but for now this is setting the plants up for growth.
